Wine does support unicode, and one of the steps you listed (1 or 2) is required (it's not different from Windows in that regard) to properly display appropriate character set, along with fonts with required glyphs.
Yes, Sorry, it was a dummy question. As I said above, using unifont the chinese characters are correctly displayed and even files with unicode characters are correctly saved. Definitively I think that the problem lies in the missing glyphs in the default fonts. Even winfile.exe will not display unicode filenames correctly.
